Abstract (en)

This invention provides a composition that contains PFOB with a PFOA content lower than that of known PFOB, and that is less likely to have an adverse effect on the environment; and provides a method for producing PFOB. The composition contains C₈F₁₇Brand further contains C₇F₁₅COOH, wherein C₇F₁₅COOH is present in a concentration of 25 ppb or less based on the total weight of C₈F₁₇Br. The method for producing C₈F₁₇Br comprises reacting C₈F₁₇I and a brominating agent to obtain C₈F₁₇Br, and alkali-washing the obtained C₈F₁₇Br to reduce the C₇F₁₅COOH content to 25 ppb or less based on the total weight of C₈F₁₇Br.
